Precious little is known about the distribution of the eigenvalues of any second-order linear elliptic non-self-adjoint boundary value problem in any domain in for (see Sect. 4.17). The singular perturbation asymptotics described in Chap. 3 are used here to construct an approximation to the entire spectrum of a non-self-adjoint Dirichlet problem for the Hopf vector field, singularly perturbed by a small Laplacian.
